ADJUSTABLE AUTOMATIC VALVE REGULATOR.

Application filed December '27, 1923.

To all whom it may concern:

Be it known that I, LOUIS H. Henson, a citizen of the United States, and resident of Austin, in the county of Travis, in the State of Texas, have invented certain new and useful Improvements in Adjustable Automatic Valve Regulators, of which the tollowingis a specification. V

My invention relates to improvements in valve regulators and it consists of the con- 'structions, combinations and arrangements herein described and claimed.

An object of the invention is to provide a device by means of which .a valve in a pipe line may be opened quickly and by which said valve is reseated automatically at various adjustable speeds.

-A further object of the invention is to provide ineehanism tor .a valve in a pipe line by which the valve is opened manually and reseated mechanically.

:Other objects and advantages will appear in the following specificationreference being had to the accompanying drawing, in wlrieh- Figure ,1 is a perspective view of the automatic regulator on a valve of the globe type.

Figure 2 is a longitudinal section of the structure in Figure 1 Figure .3 is a detail perspective view of r the combined intake and relief valve,

Figure 4 is a longitudinal section of the valve in Figure 3.

The invention is shown applied to a valve of the globe typegeneral-ly indicated 1. The valve may be situated in any pipeline, the

. fluidiot-whieh may be controlled in the particular manner described below. The valve member 2 is adapted to occupy .aseat 3 trom which it is lizttcd by a stem. at which carries the valve.

The elongated stem l of the valve member 2 passes through a closure cap 5 which has a cupped end- '6 to eoact with a sh ilar cup 7 on the cylinder 8. The cup 7 has threads 9 by means of which it is screwed on the cup .6. The space or chamber provided by the cups is adapted to receive a packing.

Situated in theeylinder 8 is a piston 10 which carries a cup leather 11 in contact with the wall of the cylinder. The :upper edge of the cylinder 8 terminates in a flange ;12 beneath which the coupling 13 is swiv- .eled. The coupling secures a base 14: on top of the cylinde and the ba provides the necessary closure for the cylinder.

escape opening oi? varying size.

Serial No. 683,058.

This base, however, does not make an airtight closure for the cylinder as it has a 1:11 fe opening 15 through which the air has no play and through which both the stem and a spring 16 operate. A gasket 17 is interposed between the fiange 12 and the base 14, but this may be eliminated in actual practice if it be found that the coupling 13 will alone make a good connection.

At one side oi the base 1-1- is a standard 18 which has a bracket 19 extending toward the center of the base. The bracket has a depending boss 20 in line with the opening A cone-nut 21 which is adjustable on the threads of the boss 20 provides the support for the upper end of the spring 16. This nut furnishes the base from which the spring presses toward the piston 10. The purpose of the spring is to keep the valve member 2 seated, and the tension of the spring is transmitted to the valve member through the piston 10 and valve stem i. The valve stem is threaded at 22 to carry the nut by which the piston is supported in place.

A looped extension 2dof the standard 18 furnishes a guide for one end of the operati-ng lever 25. This lever carries a lug 26 which provides a freely movable connection between the lever and the upper end of the stem 4:. The operating lever has pivotal mounting on the upper end of a link 27 which in turn is pivotally mounted in cars 28 on the base 14.

Fitted in the bottom of the cylinder F; is a sleeve 29 which has a kerf 30 atone side. This ker't is V-shaped as shown, and tapers from top to bottom so as to present an air Aball check valve .31 gravitates on its seat at the upper end of an air inlet 32.

This inlet communicates with :1 rhmnlwr 33 which is threaded at 3-3 at the il'i plfil end to receive a hollon plug. This pliigrii nicvcnls the ball check 3i sifroin leaving the rhaniher upon the admission of air into the cylinder 8. The lower end of the plug has several slots 85 which still let the air through should the ball cheek become seated against the lower end of the plug.

The valve sleeve 29 is screwed into a boss 36 at the bottom of the cylinder 8. The position of the sleeve, and the resultant size of the air opening at the kert 30. determines the speed at which the piston 10 and valve member 2 may return upon having been moved upward by the lever 25. A check nut 37 preserves thefiadjustments of the valve sleeve. A screw 38 in the loop 2% limits the upward movement of the valve stem 4: by

V restricting the free end of the lever The operation will be readily understood from the foregoing description. The valve 2 is opened by pressing down on the right end of the operating lever 25. The movement of the lever is limited by the screw 38.

' The stem 4; raises both the valve 2 and piston I claim is 10 against the tension of the spring 16.

Air is drawn into the bottom of the cylinder 8 throughthe'valve sleeve 29, the ball check 31 being unseated by the pressure of p the inflowing air. 7 Upon releasing the operatinglever the spring 16 will force both the piston 10 and valve 2 back. However, the rapidity of the return movement is governed by freedom with which the entrapped air in the cylinder 8 can escape at the kerf 30.

If the, valve sleeve 29 is adjusted far into the base 36 so that but little of the kerf shows, the escape ofair will be slow and the return of the piston and valve will be slow. On the other hand, if the valve sleeve is adjusted far out of the base thearea of the opening at the kerf will be large. The

escape of air will therefor be rapid and the return of both piston and valve will be 7 rapid.
